摘要

．本文分析了乳状炸药在采用房柱采矿法的地下油页岩矿山爆破效率下降的相关问题。这些问题与入口提前减少、柱墙破碎和屋顶倒塌有关。研究的目的是为了提高爆破效率，保证足够的进路进度，确保矿柱和直接顶板的稳定状态。改进的爆破模式在现场条件下进行了成功的试验。结果表明，巷道掘进速度、直接顶板和柱墙稳定性均有显著提高。

A case study to improve blasting efficiency by the use of emulsion explosives

. This work analyses issues associated with the deteriorated blasting efficiency by the use of emulsion explosives in underground oil shale mines that utilise room and pillar mining methods. The problems were connected with the reduction in entry advance, shattering of pillar walls and falling of the roof. The aim of this study is to improve blasting efficiency that can guarantee a sufficient entry advance and secure stable conditions of the pillars and the immediate roof. The improved blasting pattern was successfully tested under in-situ conditions. It was demonstrated that the entry advance and the stability of the immediate roof and pillar walls were significantly enhanced as a result.
